Value Collection 724-2020 Roughing End Mill 1/4 in Cobalt

Product Description

The VALUE COLLECTION 724-2020 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel, this tool delivers the heat and wear resistance needed when cutting harder metals or running at elevated feed rates. The 3-flute geometry with a bright, uncoated finish provides efficient chip evacuation during roughing passes. It carries a 1/4 inch cutting diameter and a 5/8 inch length of cut, making it well-suited for shallow-to-moderate depth roughing work. Licensed machinists and toolroom operators typically reach for this style of end mill when a carbide tool is not required or when working in interrupted cut situations.

This end mill is appropriate for general-purpose roughing operations on ferrous and non-ferrous materials in manual or CNC milling machines. The 3/8 inch shank diameter fits standard collets and end mill holders common in vertical machining centers and knee mills. The right-hand cut and right-hand flute direction are standard for conventional milling setups. With an overall length of 2-7/16 inches, the tool fits most standard tool holders without requiring extended-reach setups. It is a single-end tool, meaning it is not reversible once one end is worn.

Key Features

• M42 cobalt construction for improved heat resistance compared to standard M2 HSS
• 3-flute design promotes efficient chip flow during roughing passes
• Bright uncoated finish suits a wide range of materials and cutting fluids
• Right-hand cut and right-hand flute direction for standard milling orientation
• Non-center-cutting geometry — requires a pre-drilled or pre-milled entry point
• Single-end configuration for straightforward toolholder setup

Compatibility

Designed as a general-purpose roughing end mill compatible with standard collets and end mill holders accepting a 3/8 inch shank diameter on vertical milling machines, knee mills, and CNC machining centers.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the 3/8 inch shank in a properly sized collet or end mill holder and torque to the machine manufacturer's specification. Because this is a non-center-cutting tool, it cannot plunge directly into solid material — use a pre-drilled hole or ramp entry. Inspect the shank and cutting edges for damage before each use and confirm tool runout is within acceptable limits before beginning a cut.
